To all who/m. tf/'nay conce/m.

Be it known that I, HOWARD L. PAGE', a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in 'Reproducers for Sound Records, of which the following is a specification.

This invention is a machine of the phonographic type for reproducing sound from a record of the type shown, `described and claimed in my original application, Serial ANo. 500,012, filed September 12, 1921, of

which this is a division.

The object of the invention is to produce a machine which will operate upon records made by said prior patent application and,

as a result thereof, deliver into the ear audible sounds substantially identical with those originally entering the recording machine.

The invention consists in a machine capable of attaining the foregoing objects,which can be easily and cheaply made, which is satisfactory in use, and is not readily liable to get out of order.

The invention further consists in many features and details of construction which will be hereafter more fully set forth in the specification and claims.

Referring to the drawings, in which like numerals designate the same parts throughout the several views:

Figure 1 showsthe reproducing machine 35 by which a commercial sound record of the type produced by the machine of said prior application is used to reproduce the original sounds. This figure isa side lview of the mechanism of Figure 2. 40 Figure 2 is a plan detail view ofthe mechanism ofFigure 1.

Figure 3 is a detail of the pivot mechanism for the record reproducing bar taken from approximately the points indicated by the arrows at 3-3 of Figure 2.

Figure 4 is an enlarged detail view of the reproducing bar showing the manner in which it contacts the reproducing record in transmitting what is on it into audible 5o sound.

Figure 5 shows an electric circuit and mechanism insertedl therein by 4which the reproducing apparatus of this invention may be used to 'produce the 'actual sounds which are on the record at any distance from lnal application, said figures are merely re- -5, comprlsln miles. -For the purpose of insuring identity `of this divisional application with the origiy the main machine, either a few feet or manyproductions of said FiguresV 23 to 27 ofsaid original application with only the figure numbers changed, the letters of reference on the figures being otherwise those of the original application.

The mechanism of the original 'application forms a record, shown in Figures 2 and a flat tape 216 supporting a thicker portlon 222 having a rightv angle' edge 172, whose irregularities really constitute the effective workingrecord, as will more fully appear from said original application.

In the use of thisinvention, it is supposed that the operator is equipped with the long strip of record 222--216 from which it is desired to produce audible sounds, as with any phonograph, and for this purpose, this record is run through a reproducing machine of the type shown in F igures'land 5, inclusive. A preferred form of the device is shown conventionally mounted inside of a case 228 `provided with record carrying` reels 230 and 232 between which the record may be passed over driving rollers 234 suitabl power actuated and an intermediate rol er 236. At one side of the case there is a large opening 238 over which fits the resonator 114, provided with an ordinary reproducing disc' 240. of metal, mica or any other commercial form of material. This resonator carries a frame 244. carrying soft rubber pivot bearings 242 between which is journaled a shaft 246 of a reproducing rod 248 adapted to contact the Aline 172 ofthe record 222 at an. angle thereto as shown in detail in Figure 4 and be held in contact therewith by a spring 250 as shown in Figure. 2. The soft rubber bearings 242 are important in absorbing undue vibrations which might affect the reproducer. This rod 248 extends transversely of the record 222-216 and completely across it and thev record is locatedl near the end of the rod so that there is ample opportunity for the rod to follow all of the small movements and variatiens of the curved lin'e 172 as the record passes under the rod thereby insuring transmission of those variations from the rod -248 through a connecting rod 252 attached 119 vvto the diaphragm240 withithe result thaty all the variations in the record 222 are transmitted to the diaphragm and consequently into the airas sound, vsuchsound being, because of the accuracy of the machine and the methods followed an exact vreproduction of the soundsv initially delivered into thev resonator'of the receiving machine.

lParticular` attention iscalled to Figure 4 which shows vexactly how therod 248 travels `only on the' edge' 172 of record' 222 as dis- .by-insuring that the recordindulations of line 172 are all accurately transmitted to the repro ducer., i'

llt is, of4 course, to be understood that the markings of -line172 inthe various drawing'are-veryL much exaggerated for purposesof illustration but records made by this method do in fact vary in the same way that they 'are illustrated and the machine does produce lin actual practice the sounds recorded. I

Figure 5 shows a modiied form of construction in which'the lreproducingbar 248 instead of operating directly upon the diaphragm 240,operates in conjunction with a transmitting vmagnet 254"'con'nected in circuit .through the wires and electrical mechanism 256 with a reproducer magnet 258 adapted to operate the diaphragm 24021 ofY a distant resonator ll4a. Under this 4construction the members 240a and 248 may bemiles apart without affecting the result.

This feature is reserved for divisional ap plic'ation, Serial No. 593,193.

Having thus fully described my inven- I tion, what l claim asnew and desire to secure by Letters Patent, is:

lln mechanism of thev class described, in combination withy a wheel carrying on fits surface a record strip carrying a record having a tp surface parallel to the atlsurface of the strip and? record indentations in its side, a'reproducing bar pivrecord and a ,reproducing diaphragm conigieaoao i nected to said lever whereby the variations in the record. are reproduced on the dia` phragm. 55 .2. ln combinationwith a normally flat movablev record having record indentations of substantial depth perpendicular. to the face of the record, a reproducing bar pivotally'mounted in the plane of and at a 60 distance from the record and contacting the corners of the indentations in the record at an angle to'A the normal flat surface of the recor 3. ln mechanism of the class described,

in `combination with a wheel carrying on its circumference, parallel toits axis, a carrier formed with a flat surface, having thereon a raisedportion, said raised portion having sound record indentations in one edge and' 70 extending in varying widthscross-wise of the carrier, the portion beingof suiiicient height above the strip to mechanically affeet the transmitting device'engaging said indentations; arcproducing bar, pivotally mounted at one side of the wheel and ex-A tending onto said carrier, in contact -with said indentations, at an angle tothe upper surface of the carrier, and a reproducingA diaphragm connected to said lever whereby 80. 4the variations in the record are reproduced on the diaphragm.

4. In mechanism of the class described,l in combination with awheel carrying on its circumference, parallel to its axis, a carrier fo-rmed with a flat surface, having thereon a raised portion, said raisedcportion having sound record indentations in one edge at right angles to the surface of the carrier and extending in varying widths crossawise of the carrier, the portion beino of sufficient height above the strip to mec anically affect the transmitting device engaging said indentations; a reproducing bar, pivotally mounted at one side of the wheel and extending onto the carrier, in contact with said indentations, at an an le to the upper surface of the carrier, an a reproducing diaphragm connected'to said lever whereby the variations in the record arereproduced 10-0 on the' diaphragm. l

In witness whereof, l have hereunto-subscribed my name.
